Ralph de la Vega [pictured], President and Chief Executive Officer - AT&T Mobility, said "Overall more than 70% of our smartphone base has moved to usage-based plans and data use on the smartphones is growing by about 50% year-over-year, so we have more smartphones on usage-based plans, data growth is strong and growing number of subscribers are taking bigger buckets of data from us. About 80% already take the larger data plans and we are seeing more than a quarter of mobile share accounts on data plans of 10 gigabytes or higher".

"In terms of wireless data and people hitting the caps or bumping against them. We are not seeing a lot of that. What we are seeing, which is part of our strategy all along, Tim, is we know that there is an explosion going on with tablets. Our firm believe, all the time, was we needed to get mobile share out in the market place, so customers could easily add a tablet and at the time they add the tablet, then the increase to size of the data bucket. That's exactly what is happening".
